1992: The Vatican admits erring for more than 359 years in formally condemning Galileo Galilei for entertaining scientific truths such as the Earth revolves around the sun, which the Roman Catholic Church long denounced as anti-scriptural heresy. Pope John Paul II himself met with the Pontifical Academy of Sciences to help correct the record. In 1633, at age 69, Galileo was forced by the Roman Inquisition to repent and spent the last eight years of his life under house arrest.
